To all whom it may-concern:

Be it known that-I, FLonENon B. MYnns, a citizen of the United States, residing at Minneapolis, in the county of Hennepm and State of Minnesota, have invented certain new and useful Improvements in- Building Blocks, of which the following is a specification.

My invention relatesto building blocks mortar and which wall will have a continuous passageway extending from top to bottom', and also horizontally,'and adapted to be filled with li uidcement for permanently holding the bloc s together in the wall. Another object isto provide a block having air spaces and channels so arranged that when the wall is laid there will be a continuous passageway therein extending from top to bottom, and also horizontally for passa e of air'whereby the wall will be effectively ventilated, thus preventing the'accumulation of moisture therein.

The full objects and advantages of my invention will a pear in connectlon with the.

detailed description thereof and the novel features embodied in my inventive idea will be articularly pointed out in the claims.

11 the accompanying drawings, which illustrate the application ofm invention,-

Fi 1 is a top plan view 0 a portion of a wa 1 made from my blocks and also showing the construction at one corner of the wall. Fig. 2 is an end view of one of my blocks. Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1. Fig. 4 is a longitudinal section on the line 44 of Fi 1 before puddled cement is poured in. Figro is a similar view showing the puddled cement in place Fig. 6 is a transverse section on the line 66 of Fig. 1. Fig. 7 is a transverse section on the line 7-7 of Fig. 1

showing the wall provided with means for assisting in ventilation. Fig. is a top plan view of a portion of a wall with the blocks "laid the other side up from that shown in Fig. 1. Fi 9 is a transverse section on the line 9-9 0? Fig. 8 and showing the vertical passageways fi led with cement. Fig. 10 IS a view similar to Fig. 9 showing a slight modification. Fig. 11 is a top plan view of a portion of a wall in which curved blocks are used for constructions such as silos.

My block is made of cement or other plastic material and, as shown in the drawings, embodies the same idea and arrangement in regard to air spaces and interlocking whether in the form of rectangular blocks, corner blocks or curved blocks. As shown provide a block having the two opposite side portions 10 and 12 connected by an intermediate portion 14, the latter portion being raised, as best shown in Figs. 2 and 6. The two side portions are provided with a pair of vertical air spaces 16 and the intermediate portion is provided with a vertical space 18 which, as shown, is oval in form. The intermediate raised portion on its upper side has a pair of longitudinal ribs 20 and 22 adapted. to extend up into the bottom of a superposed block so as to abut with shoulders 24 and 26 thereon. This provides for interlocking engagement of the blocks vertically when they are laid up into a wall. The two portions 10 and 12 are provided at one end of the block with vertical recesses 28, and at the other end with corresponding projections 30. The projections 30 fit into the recesses 28 of the adjacent block lying in the same course when the blocks are laid up into a wall whereby the blocks are locked together horizontally. Between the ribs 20 and 22 the intermediate portion is formed with a concave recess 32. It is, therefore, apparent that there will be longitudinal passageways 34 as shown in Fig. 6 extending between the courses and these passageways will join all of the ver-- tical spaces 18. The intermediate portion of the block is further provided at each end with a semi-circular recess 36 sothat when the blocks are laid the two recesses of adjacent blocks come together and form circular spaces 38. As will be apparent from Fig. 1, when the courses are laid in staggered relation in the usual'manner spaces 38 of one course will lie directly underneath the oval spaces18 of the superposed course. The upper surfaces of the side portions '10 and 12 are rovided with longitudinal grooves 40 an 42 so that when the blocks are laid the vertical'spaces 16 will be connected by ion. 'tudinal passageways for circulation of an. Corner blocks are-formed as shown in Fig. 1 by providing a construction in which one end of the block is arranged at right angles to the other end. In

" laying up a wall with my blocks a suitable portions of the blocks.

base B is first provided and the blocks are laid upon this baseand upon each other in superposed courses with the blocks in succeed- 1ng courses laid'in staggered relation. The

blocks will be held together both vertically and horizontally in the manner previously stated, and the use of mortar between joints may thus be entirely dispensed with. When the wall has been completed, or at any time when considered desirable, puddled cement is' poured into the openings in the intermediate portions of the blocks constituting the upper course andthis cement on account of the-passageways connecting the openings in the manner previously described will flow into the openings of the intermediate block portions of the lower course. As is apparent from Fig. 5, this causes the intermediate portion of the walls to be of the nature of monolithic construction, it being noted that the cement fills the spaces 18 and 38 and the passageways 34. As shown in Figs. 8 and 9, the blocks may be laid the other side up if found desirable. Fig. 10 shows a slight modification for use in case it is desired to point up the wall. Depressions 44 are formed at the upper and lower edges of the blocks and these depressions if desired may be on both the-inside and outside faces. After the wall is laid these depressions are filled in with mortar or cement. Fig. 7 shows how my wall may be adapted for ventilation. A special block 46 is provided for the lower course. This block has a passage 48 connecting two air spaces of the inner and outer portions of the block, while the air space 16 nearest the inside of the wall is provided with openings 50 which constitute a register. A similar block 52 is provided in one of the upper courses. In this block there is a passage 54 connecting two air spaces of the innerand outside portions of the block, while the air space nearest the outside of the wall is provided with openings 56 which constitute a register. On account of this construction it is obvious that complete circulation of air is provided through all of the air spaces of both the side In the form of invention shown in Fig. 11 the blocks are constructed in the same manner as previously described except that they are curved'instead of bein rectangular. Since this view is similar to ig. 8, the same reference numerals with the prime mark added are used.

I claim:

1. A building block having two side portions and an lntermediate raised portion, longitudinal ribs on one face of the block which limit the sides of said raised portion and enclose between them a concaved longitudinal recess extending from one end of the block to the other in said raised portion, and curved shoulders on the opposite face of the block with which ribs on adjacent blocks corresponding to the above mentioned ribs are adapted to fit, said shoulders being located outwardl from the two longitudinal sides of said raised portion, each of said side portions containing two vertical air spaces positioned at equal distances from the two ends of the block and having a longitudinal groove along its middle on one face of the block connecting said air spaces, said block having a vertical opening at its center and a vertical recess at the middle of each of its ends whereby vertical passageways will be formed in the wall when the blocks are laid in staggered relation in courses.

2. A building block having two side portions and an intermediate raised portion, corresponding lugs and recesses on opposite ends of said side portions, longitudinal ribs on one face of the block which limit the sides of said raised portion and enclose between them a concaved longitudinal recess extending from one end of the block to the other in said raised portion, and curved shoulders on the opposite face of the block with which ribs on adjacent blocks corresponding to the above mentioned ribs are adapted to fit, said shoulders being located outwardly from the two longitudinal sides of said raised portion, each of said side portions containing two .vertical air spaces positioned at equal distances from the two ends of the block and,

having a longitudinal groove along its middle on one face of the block connecting said air spaces, said block having a vertical opening at its center and a vertical recess at the middle of each of its ends whereby vertical passageways will be formed in the wall when the blocks are laid in staggered relation in courses.

In testimony whereof I hereunto affix my signature.
